Trane RTU YCD075

In all my years in the HVAC world i never thought I would run into a simple low vol. wiring problem but I am baffled. I have a Trane YCD075 roof top unit and am tryin to wire a trane non programmable zone sensor/ tsat to it but do not understand how to wire it to the teminal strip. I tried wiring it to the same terminals the programmable stat was wired to with no prevail. Also the wiring diagram on the door is destroyed... thanks a whole lot trane for putting the schematic on a door that recieves weather damage! Any help on this situation would be great.... THANKS!!!

i had one like this a few years ago..i dont remember how i wired it but i had to talk to trane ENGINEERS not just tech support. seems the directions they gave with sensor was FUBAR. My advice call trane.

I don't have time this morning to research this, but I was under the impression that a YCD unit is a Precedent series, and has Reliatel. That would mean the poster is trying to connect to the same terminal strip along the edge of the boards where he found a conventional stat, and he should instead be using the strip for the trane zone sensor.
